Read the text once.  \nPenguins are special birds that can’t fly. Most penguins live in Antarctica. A long time ago, penguins adapted to life in the water instead of the air. Their wings became strong, flipper-like tools that help them swim instead of soar above the land. Penguins are excellent swimmers, and their bodies are built for gliding through the water. Their smooth shape, strong muscles and flippers make them fast and graceful as they chase fish, squid and other food.  \nFlying takes a lot of energy, and penguins don’t need to fly to survive. They get most of their food from the ocean, so being great swimmers is more important. Instead of the hollow bones that flying birds have, penguins have heavier bones. These help them dive deep underwater without floating back up too quickly.  \nOn land, penguins waddle because their short legs are not built for running or jumping. Even though they can’t fly, penguins have other ways to move. Some slide on their bellies across the snow, which is a fun and fast way to travel on the ice.  \nPenguins can’t fly, but they don’t need to.  \nTheir amazing swimming skills and unique bodies help them survive in their cold, icy homes. Penguins remind us that animals are built to fit their environment perfectly!  \n2. Read the text a second time. This time, underline the main idea and circle the supporting details.  \n3. Then answer the following questions:  \nWhat is the text’s main idea?  \na. Penguins are special birds that can’t fly.  \nb. Penguins are excellent swimmers.  \nc.
